[0002]

2. Description of the Related Art Conventionally, the amount of electric power consumed in a general house is calculated based on the display data of an integrated wattmeter installed in each house by a meter reader of an electric power company or an electric power collection company commissioned by the electric company. It is a common practice to read the data periodically to determine the difference between the previous display data and the present display data, and to bill for the electricity based on the data.

Accordingly, various costs such as labor costs, transportation costs, insurance premiums and the like for meter readers are incurred. In addition, since meter readers measure the integrated power meters of many houses,
Although the probability is small, there is a problem that an erroneous needle reading due to a reading error may not occur. The present invention solves the above-mentioned conventional problems by transmitting the meter reading of the electric power consumption by the meter reader to a central device as necessary using a distribution line which is a power supply for a general house. Is what you do.

FIG. 1 is a conceptual diagram of a system for collecting power consumption data according to the present invention, wherein 1 is an electricity bill collection company, 21 to 2n are ordinary houses, and the electricity bill collection company 1 collects electricity consumption data. It is located under management. Between the electricity charge collection company 1 and the general houses 21 to 2n,
It is connected to a general house by a distribution line 3 and a distribution line 4 for supplying power from a substation of a power company. The electricity charge collection company 1 is provided with a power consumption data collection device 5 for collecting data of power consumption, and a general house has a power consumption measurement device 6 including a data counting unit for counting power consumption. Is provided. Reference numeral 7 denotes a utility pole or the like.

Next, the power consumption data collection device 5 provided in the electricity bill collection company 1 and the power consumption records provided in the general houses 21 to 2n, respectively, are shown in the conceptual diagram of the collecting system shown in FIG. The device 6 is shown in FIGS. The power consumption collecting device 5 shown in FIG. 2A is used to have the power consumption measuring device 6 provided in the general houses 21 to 2n transmit the power consumption data consumed during a predetermined period. Spread spectrum signal transmitting section 51 for transmitting a polling signal, and spread spectrum signal transmitting section 51
And a spread spectrum signal transmitted from the power consumption measurement and recording device 6 based on the polling signal and received via the distribution line superimposing section 52. A receiving unit 53, a storage unit 54 such as a magnetic disk for storing the transmitted power consumption data of each general house, a printer 55 for reading out the storage data of the storage unit 54 and creating an electric bill, etc. A microcomputer control unit 56 for controlling each component is provided.

The power consumption measuring device 6 shown in FIG. 2 (b) is a counter 61 for integrating and counting the power consumed by the electric equipment in the house, and transmitted from the power consumption collecting device 5 via the distribution line 3 and the like. A spread spectrum signal receiving section 62 for receiving a spread spectrum signal which is a polling signal to be received; a spread spectrum signal transmitting section 63 for transmitting power consumption data counted by the counting section 61 based on the polling signal; A distribution line superimposing section 64 for superimposing transmission data of the spread signal transmitting section 63 on the distribution line 3 and a microcomputer control section 65 for controlling these components are provided.
Note that the filter 66 controls whether the polling signal transmitted from the power consumption data collection device 5 or the spread spectrum signal of the power consumption data transmitted by the own spread spectrum signal transmission unit 63 affects electric equipment in the house. It is provided so as not to affect.

In spread spectrum communication, usually,
Carrier waves were subjected to two-phase modulation with information data and compared with the data, and then subjected to two-phase modulation with a pseudo-random code having a higher signal transmission rate and transmitted, or multiplied by a pseudo-random code and data. At the output, the carrier is two-phase-modulated and transmitted as a spread signal. By taking advantage of its strong noise resistance, data can be superimposed on existing distribution lines and transmitted by remote control. In addition, in order for the power consumption data collection device 5 to collect the power consumption data, the power consumption measurement device 6 of each house is required.
The polling signal based on the spread spectrum signal is transmitted to the mobile station at predetermined intervals, for example, every one month or two months. Data is collected and collected, and an electricity bill is created based on the stored data. It is possible to eliminate the need for a meter reader by sending the mail to a demander of each house by direct mail or the like.

[0009]

As described in detail above, according to the power consumption remote logging method of the present invention, a meter reading member is not required, so that labor costs and the like are not required, and the power consumption data collection device is not required. Signals are exchanged with each power consumption measuring device using a pseudo-random code, so that the other party can be confirmed without fail, and power consumption data can be read directly electronically, so there is no erroneous request. This has the effect that the collection process is performed very quickly.
